Resolving PXRedirectRequiredException Issues in Custom Acumatica Processing Screens

When developing custom processing screens in Acumatica, it’s not uncommon to encounter challenges that disrupt the expected functionality. One such scenario involves using the PXRedirectRequiredException to display a report after processing, which can interfere with the standard processing screen behavior.

Let’s explore this issue, the underlying causes, and a practical workaround to ensure your custom screen works seamlessly while delivering the desired functionality.

The Problem: Interruption During Processing

In a custom processing screen, a report was generated at the end of the processing by throwing a PXRedirectRequiredException as shown below:

if (results.GetRowCount() > 0) 

{ 

    throw new PXReportRequiredException(results, "IC604010", PXBaseRedirectException.WindowMode.NewWindow); 

} 

While the report opened in a new window and displayed correctly, this implementation caused two significant issues:

1. The processing popup failed to display, leaving users unaware of the progress.
2. The grid of items available for processing did not refresh, preventing the removal of processed items.

When the exception was commented out, the standard processing screen behaved as expected. However, the report functionality was lost.

Investigating the Root Cause

Further testing revealed that the timing of the PXReportRequiredException was key to the disruption. If the exception was thrown too quickly, it interrupted the standard processing flow, leading to the issues described.

The Solution: Adding a Pause

To address this, a simple but effective solution was implemented: introducing a delay before the report generation. Adding a pause allowed the processing logic to be completed before the report was triggered.

Here’s the adjusted code:

System.Threading.Thread.Sleep(5000); // Add a 5-second pause 

if (results.GetRowCount() > 0) 

{ 

    throw new PXReportRequiredException(results, "IC604010", PXBaseRedirectException.WindowMode.NewWindow); 

} 

By delaying the execution of the exception, the processing popup displayed correctly, and the grid refreshed as intended.

Key Takeaways

1. Timing Matters: Throwing exceptions like PXRedirectRequiredException too early can disrupt Acumatica’s standard processing flow.
2. Practical Workaround: Introducing a small delay (e.g., using Thread.Sleep) can resolve timing conflicts, ensuring the screen behaves as expected.
3. User Experience is Crucial: Always test customizations under different scenarios to ensure smooth functionality for end-users.

Final Thoughts

While adding a delay may not feel like the most elegant solution, it is a pragmatic approach to maintaining the balance between custom functionality and system integrity. If you’re developing customizations for Acumatica, always consider how timing and exceptions might affect the overall user experience.

For further refinement, consider exploring alternative methods to trigger reports post-processing without relying on timing-based solutions. Acumatica’s extensibility provides numerous possibilities for innovation!
